scanners to clean a persons machine

hello,
today someone said there pc was fast on friday when they first got the internet now its really slow.
so im helping him out and cleaning the crap out so far ive got,
autoruns
process explorer
hoster
kis6.0 mp1
dr web cureit
nod32 2.7
unlocker
superantispyware
a squared free.
.....
any other apps that could be useful and dont take to long to run?
i will only install one av at a time.
im gonna try and clean out as much as possible with the internal bases of the programs above before i put it on a network.
which means most of the programs will be out of date.
dr web cureit ive just downloaded so its got quite recent defs.
he is gonna bring the pc in to college so i can run all the tools to clean it.
thats why i noted about not going on the internet intill most of it is clean.
i have got the kaspersky zip files which i will use to update kav6.0 at there pc.

i dont know about quick-fixes, but

id recommend running a scan with perfectdisk and tuneup and obviously run dr.web cure it, and that should be it

 

Ewido Micro ...

And don't forget
MS Rootkit Revealer (for rootkit scan , appropriate for even a less knowledgable person)

your right i shouldnt have to do many scans.
the last pc i cleaned for an idoit at college i used autoruns to get rid of most of the startup crap.
i used process explorer to see what processes are running.
and used dr web cureit i downloaded at the time he asked me for help.
that was all i had time for lol.
the dr web scan is good but it takes ages.
i might try nod32 first since the scan is alot faster and ive heard thats what other people do since its such a fast scan.

@Hitech boy doesnt ewido micro need the internet on that pc to update?
if so i might use the avg antispyware version with old bases.

HijackThis?

 

Yes . You can use it after you plug the machine to the network .
Is that computer so bad ?

 

i have no idea i havent seen it yet im thinking the worst of it lol.
but i could plug it in after.

AntiVir 7 + Kaspersky + DrWeb CureIt

That should effectivelly do it.

 

can you update antivir with zip files?
what about kav+dr web cureit+nod32+antivir workstation?
is downloading the workstation version of antivir ok? does it need a key?
if i use my antivir key i got free in it can i remove the key easy?
i dont want him using my key after that lol

ok so ive got the following
scanners:
nod32
kav6.0 (with zip updates)
dr web cure it
antivir premium
...................
other stuff:
process explorer
autoruns
unlocker
i need to get him firefox with no script.

Yep sure can:-forum.antivir-pe.de/thread.php?threadid=12073"

Also "Killbox" might be useful for any stubborn problems.
